ERROR:pms:Sensor is not PMS5003T
The buffer seems to be too long, as if your PMS5003T did not recognized the passive mode command.
Are you using the rpi's serial pins? Did you connect both RT and TX lines?

Yes I'm using both RX and TX (and nothing else, just the power is connected).

I can not find a valid header/message on this hexdump.
Can you set the baud rate to 9600? I think the command is stty -F /dev/ttyAMA0 9600
